Describe the bug

Admin scripts fail to enqueue on front end, breaking the admin bar button

Site information

Popup Maker version: 1.13.1

WordPress version: 5.5.3
PHP version: 7.4.1

Expected behavior

popup-make/assets/js/admin-bar.js should load as long as Disable Popups Admin Bar is disabled in settings.

admin-bar.js, using the handle 'pum-admin-bar' fails to load. Query Monitor states "dependency missing"

Steps to reproduce

1. Enable Popup Maker
2. Visit front end page

Errors

Additional context

Was able to fix by adding to includes/modules/admin-bar.php, line 23:
add_action( 'wp_enqueue_scripts', array( __CLASS__, 'enqueue_files' ) );
